Kevin Van de Velde commented on DS-1281:
----------------------------------------
The actual cause of the issue is a java 7 error, but the fact that the
XmlWorkflow classes are called when it isn't enabled is wrong. To fix this I
have created the following pull request:
https://github.com/DSpace/DSpace/pull/96
Ps: A fix for the actual error will follow shortly.
> XMLWorkflow throws NullPointerException on "Assign Roles" when not enabled
> --------------------------------------------------------------------------
>
> Key: DS-1281
> URL: https://jira.duraspace.org/browse/DS-1281
> Project: DSpace
> Issue Type: Bug
> Components: XMLUI
> Affects Versions: 3.0
> Reporter: Tim Donohue
> Assignee: Kevin Van de Velde
> Priority: Major
>
> This is occurring on the demo.dspace.org server's XMLUI interface, currently
> running 3.0-rc1
> To reproduce:
> 1. Setup DSpace 3.0-rc1. Keep XMLWorkflow disabled (as it is by default)
> 2. Create a Collection in the XMLUI
> 3. Edit the Collection
> 4. Click on the "Assign Roles" tab
> No error appears in the UI, but the log file will now show a
> NullPointerException that looks similar to this:
> 2012-10-10 20:53:27,746 ERROR org.dspace.xmlworkflow.WorkflowFactory @ Error
> while retrieving workflow for collection: 10673/19
